l6 claims. (ci. 229-40) This invention relates to improvements inpackaging l cartons including cartons desirable for packaging productssuch `as sliced bacon and the like which is relatively heavy inproportion to the dimensions of the product.

The main objects of this invention are:

First, to provide a carton for packaging products such as food productswhich is of generally parallelogram shape viewed endwise and at the sametime is effectively resistant to load crushing or distorting stresses.

Second, to provide a carton having these advantages formed of a singlecut and scored blank of container board which may be of relatively lightstock and is strong `and rigid when erected and may be repeatedlyhandled without distortion.

Objects relating to details and economies of the inven- 'tion Iwillappear from the description to follow. The

invention is deiined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in theaccompanying drawing, in which:

Fig. 1 is a front perspective view of an erected carton embodying myinvention.

Fig. 2 is an end elevational View thereof, portions being broken away toconventionally illustrate sliced bacon or the like.

Fig. 3 is an enlarged fragmentary view in vertical section on Ia linecorresponding to line 3-3 of Fig. 2.

Fig. 4 is a fragmentary perspective view illustrating steps in erectingthe carton.

Fig. 5 is a plan view of the blank, the scoring thereof beingconventionally illustrated.

In the accompanying drawing I have illustrated my invention as embodiedin a carton adapted for the packaging of sliced bacon or the like whichis conventionally illustrated at 1 in Fig. 2 of the drawing.

The embodiment of my invention illustrated comprises a bottom 2, frontwall 3 hingedly connected thereto by the score line 4. The inner rearWall member 5 is hinged- 1y connected to the rear edge of the bottom bythe folding score 6. The cover 7 is hingedly connected to the front wallby the score 8. At its swinging edge the cover is provided with an outerrear 'wall member 9 hingedly connected thereto by the hinging score 10.This outer rear Wall member 9 is provided on its bottom edge with aclosure flap 11 which is hingedly connected thereto by the score 12 andis adapted to be folded upon the underside of the bottom as isillustrated in the drawing.

The inner end wall members 13 are of parallelogram shape and arehingedly connected to the ends of the bottom by the score 14. The frontwall 3 is provided with end aps 15 hingedly connected thereto by thescores 16 yand connected to the adjacent ends of the inner end wallmembers by the foldable aps 17 dened by the perforations 18, that is,the perforations result in the folding of the parts 17 on predeterminedlines.

At their rear ends the inner end wall members 13 are outer edges toprovide tongues 20. These tongues are insertable through the angledslits 21 in an inner rear wall member with the tongues lockinglyengaging the portions of the rear wall above the angled portions of theslit, as is illustrated in Fig. 3. 'I'his provides an eifective supportfor the inner rear wall member and also a support for the inner end wallmembers as well as providing an effective closed joint between theseparts.

The top is provided with outer wall members 22 hingedly connectedthereto by the scores 23. These outer wall members are connected to theend flaps 24 which are hingedly connected to the ends of the outer rearwall members by the scores 25 by means of the folding members 26. Theouter wall members and the ends flaps 24 are, in effect, continuous, theperforations 27 result in folding on predetermined lines.

The outer end wall members 22 are conformed to provide rear portions ofa vertical Width substantially oorresponding to the vertical width oftheinner side wall members and front portions of substantially reducedvertical width. The rear portions are provided with forwardly projectingtongues 28 on their front edges. The closure flap 11 is provided withanchoring flaps 29 at the ends thereof. These iiaps 29 are foldableupwardly upon the said rear portions of the outer side wall members and`are provided with rearwardly facing tongues 31 interlockinglyengageable with the tongues 28 thereof with the upper ends of theanchoring flaps 29 disposed between the inner and outer wall membersinto supporting engagement with the top. The front edges of theseanchoring flaps are exposed for engagement at the outer side Wallmembers, thereby facilitating the closing and the opening of the carton.

In the embodiment illustrated the top wall is provided with a window 32of substantial size, the window being provided with a transparentclosure, conventionally illustrated at 33. With this arrangement ofparts the carton may be partially erected the contents placed thereinand -the cover swung to and secured in closed position. The manualmanipulations required are easily and quickly performed.

I have illustrated and described my invention in a highly practicalembodiment thereof. I have not attempted to illustrate other adaptationsor embodiments which I contemplate as it is believed that thisdisclosure will enable those skilled in the art .to embody or adapt myinvention as may be desired.
